5 cracking of a chimney enclosed flue.

Another object of the invention is to provide a ventilating arrangementfor a building structure.

The third object of the invention is to provide a system of ventilation,whereby moisture and the like normally present in the basement or cellarof a building structure is removed.

The chief feature of the invention consists in the provision of certainarrangements in the building structure, whereby each of the aforesaidobjects is accomplished.

Other features of the invention will appear more fully hereinafter.

The full nature of the invention will be understood from theaccompanying drawing and the following description and claims:

In the drawing, Fig. 1 is a central sectional view through a chimneyenclosed flue and a building structure included in a part of thebuilding structure, the same being represented as of a single floor typeand provided with a basement or cellar.

Fig. 2 is a transverse sectional View of a chimney enclosed flue, theventilating passage therebetween and the inlets to said passage.

In the drawing 10 indicates a cellar or basement floor, 11 aconventional heating system, such as a furnace, having the smoke pipe12. The latter communicates with the flue 13 near its lower end. Theupper end 14 extends above the structure and'herein is shown terminatingabove the top 15 of the chimney 16. The chimney is shown of conventionalconstruction, such as brick work. The flue may be of conventionalstructure and in the present form of the invention is shown of heavymetal pipe, although it may be of inter-connected tiles. The chimneyencloses the flue 13 and is spaced therefrom forming a ventilating andcooling channel therebetween, said channel being indicated by thenumeral 17.

In the building structure, 18 indicates the ceiling of the cellar andthe first floor of the said structure. 19 indicates the plaster, 20 thelathing and 21 the ceiling structure of the first floor. If a one-storystructure is provided, 22 indicates conventionally the roofing thereof.If additional floors are included in the structure, they would besuperposed thereon, while the roofing would be mounted on the upperceiling or rafters if a peak roof were employed.

The projecting upper end of the flue 13 is herein shown supporting ahood 23 in spaced relation above the end 15 of the chimney. Herein thetop of the chimney is provided with a complementary structure 24.forming with'the hood a discharge passage or outlet 25 of peripheralchar- 5 actor and downwardly and outwardly pitched and communicating atits interior with the ohan nel 17.

Adjacent the ceiling or the roof of each floor, there is provided aninlet passage 26 to each room 10 or to the same room. 'Each inletpassage 26 is provided with a plurality of baffles 27 arranged in offsetand staggered relation. The inlet end of each of the inlet passages maybe provided with a register construction 28, whereby the de- 5 gree ofair removed may be regulated.

The system normally operates as follows: The flue 13 is always hot whenthere is a fire in the furnace 10 or equivalent heating system. Air inthebuilding structure is hottest at the top 20 of the room and thisheated air passes out through the registers into the inlet passage 26and through the bailie arrangement 27 and discharges into the envelopingchannel 17. The resultant action, therefore, is that the rising aircolumn 25 not only discharges through the outlet passage 25 butsimultaneously therewith maintains the brick work 16 in a relativelycooled condition and the air rising through the channel conveys the heatfrom the flue away from the same and with- 30 out transmitting it to anyappreciable degree to the brick work. In the ordinary flue and chimneyconstruction, the brick work not only envelopes the flue but in additionthereto, is in direct contact with the flue so that the heat of 35 theflue and the gases therein are transmitted to the brick work resultingin the cracking of the brick work, which structural failure invariablycauses a similar structural failure in the flue since the brick work isusually cemented to the flue.

The present invention, therefore, reduces the fire risk due to defectivechimneys and flues to a minimum.

While the invention illustrated herein is constructed of brick andmetal, it will be evident that 45 the outer portion of the chimney,shown as brick in Fig. 1, could be made of metal and the inner portionor flue could be made of interlocking flue tile without departing fromthe broader phases of the invention and both may be made of tile 50 orbrick or both may be made of metal.

The discharge of'the air from the rooms of the structure to the channel17 also insures a better air supply in the structure.

If and when desired, there may be provided at 55 the base of the channel17 a power driven device for facilitating the discharge of air throughthe channel. Herein there is conventionally illustrated the fan 29driven by a motor 30.

To prevent condensation upon the cellar walls since, as a general rulethey are cooler than the air and particularly during the late spring andearly fall, the chimney is provided with additional inlet passages 31provided with a baffle arrangement 32 and, if desired each is providedwith a register construction 3.

The air in the basement or cellar is sucked into the channel 17 by thefan and thus the air is circulated in the cellar and takes .up themoisture upon the walls that would normally condense thereon and thevapor laden air is discharged by the channel 17.

One form of the invention has been here-in illustrated and described inconsiderable detail. It is to be understood that the same is merely forthe purpose of illustration and various modifications thereof willreadily suggest themselves to those skilled in the art to which thisinvention relates, and it is to be understood that such modificationsare all considered to be within the broad purview of this invention,reference being had to the appended claims.

The invention claimed is:

1. In a fire protection heating and ventilating system for a building,the combination of a vertical flue arranged for connection at its lowerend to the smoke pipe of a furnace and discharging to the atmosphereabove the building, a chimney in spaced and enveloping relation to saidflue and forming a channel therebetween and completely enveloping theflue, said chimney extending at its upper end above the building andterminating below the top of the flue and terminating at its lower endbelow the bottom of the fiue, a passage near the room ceiling of eachfloor level and communicating at one end with the channel for foul andheated air discharge from the room, and means associated with eachpassage for controlling the discharge therethrough to the channel, thetop of said channel constituting the sole outlet therefor, an auxiliarypassage connection to the channel near the bottom thereof, and poweroperable means in the bottom of said channel for drawing airthrough theauxiliary passage and inducing forced passage of air through the channelto increase the cooling effect upon said flue suction upon the roompassage to increase air circulation through the room.

2.1m a fire protection heating and ventilating system for a building,the combination of a vertical flue arranged for connection at its lowerend to the smoke pipe of a furnace and discharging to the atmosphereabove the building, a chimneyin spaced and enveloping relation to saidflue and forming a channel therebetween and completely enveloping theflue,'said chimney extending at its upper end above the building andterminating below the topcof the flue and terminating at its lower endbelow the bottom of the flue, a passage near the room ceiling of eachfloor level and communicating at one end with the channel for foul andheated air discharge from'the room, bafile means in each passage and aregister means associated with the room end of each passage, the top ofsaid channel constituting the sole outlet for the channel, additionalpassage means connected to said channel near the bottom thereof, andpower operable means for drawing air through the auxiliary passage andinducing forced passage of air through the channel to increase thecooling effect of said flue and suction upon' the room passage toincrease air circulation in the room.
